Men Of Science In Texas, 1820-1880: V, S. W. Geiser
Field and Laboratory
A collection of short biographies of naturalists in Texas during the years 1829 thru 1880, from Norris to Zink.

The Natural History Of Necturus: Iii. Food And Feeding, Joseph P. Harris Jr.
Field and Laboratory
Necturus normally forage at night, when they leave their favored hiding places and move slowly over the bottom seeking food. Slow, undulating movements of the tail propel them; the legs seem scarcely used.

On October 14, 1957, the charter of The Graduate Research Center, Inc. was approved and filed in the Office of the Secretary of State at Austin, Texas. In the words of the charter, "this corporation is formed to support and encourage the advancement of knowledge in the pure and applied sciences, and to aid in the conduct of research and investigations in those fields at Southern Methodist University."

The First Noted Occurence Of Dasypus Bellus In Texas, Bob H. Slaughter
The First Noted Occurence Of Dasypus Bellus In Texas, Bob H. Slaughter
Field and Laboratory
A small group of persons, "The Dallas Prehistorical Society", has for several years been collecting fossil bones from the sec-ond of a series of alluvial terraces of the Trinity River. We have assembled a rather extensive fauna. Our fauna! list has not been published in full, although some specimens have been reported as new species. As some time will elapse before the fauna! paper will be ready for publication, it seems well to report here the first Texas record of Dasypus bellus (Simpson).

The Natural History Of Necturus: Ii, Joseph P. Harris Jr.
Field and Laboratory
Necturus has permanent external gills, simple internal lungs, and a skin well supplied with blood vessels; all of which have been reported functional in respiration.
Foraminiferal Populations Of The Goodland Formation, Tarrant County, Texas, Leslie R. Beddoes Jr.
Foraminiferal Populations Of The Goodland Formation, Tarrant County, Texas, Leslie R. Beddoes Jr.
Field and Laboratory
Recent studies of foraminiferal populations of the Gulf of Mexico made by Phleger (1951 and 1954), Parker, et al. (1953) , Lowman (1949), and Shepard and Moore (1955) show that different kinds of Foraminifera inhabit waters of different depth, salinity and temperature. These studies should provide evidence from which micropaleontologists may infer the nature of ancient environments, assuming always that fossil Foraminifera had the same habits as their nearest of kin in the modern assemblages. Albritton, et al. (1954) and Curtis (1955) have made quantitative studies of ancient populations, and have found that the Foraminifera tend to corroborate and supplement …

Men Of Science In Texas, 1820-1880: Ii, S. W. Geiser
Field and Laboratory
In the last issue of Field & Laboratory (26, 86-139) appeared the first 331 sketches (Abadie to Gilbert) of collectors, explorers, and observers, in a series that will extend through several issues. My fears of omissions were justified: I find that a sketch of Samuel Botsford Buckley (1809-84), a graduate of Wesleyan University in Connecticut, and twice State Geologist of Texas (1866-7 and 1874-5) was unaccountably omitted. This omission is the more notable since for twenty years I have been holding in abeyance the publication of a sketch of Buckley (on whom I have very extensive materials) waiting for a …
The Geology Of The Lancaster Quadrangle Of Dallas And Ellis Counties, Texas, Jerome J.C. Ingels
The Geology Of The Lancaster Quadrangle Of Dallas And Ellis Counties, Texas, Jerome J.C. Ingels
Field and Laboratory
Location.-The Lancaster Quadrangle is in southwestern Dallas County and northwestern Ellis County. It is bounded on the north by parallel 32 ° 37' 30"; and on the south by parallel 32 ° 30' 00"; on the west and east by meridians 96° 52' 30" and 96° 45' 00", respectively. Methods of Study.-The field work was done during the summer and fall months of 1956. A state highway map of Dallas and Ellis counties was used as the base map for this study. The geology was plotted on aerial photographs and later transferred to the base map with the aid of …

The Natural History Of Necturus: I. Habitats And Habits, Joseph P. Harris Jr.
Field and Laboratory
The mudpuppies are entirely aquatic; in habits they are more fish than amphibian. Their legs are weak, and they are nearly helpless on land.
